Fractional Coeffecient: When the Coefficient is a fraction.
Use Distibutove property: Take Then number outside () and times it by each one of the values in ()
For powers you add all the variables and thats your power.
If you have a number-variable and a number you add the numbers and keep same variable.
Problem: 2x(3x²+4x+7) First set: 2x times 3x²=(2·3·x·x·x) which is 6x to the third power. Second set: 2x·4x=(2·4·x·x) which is 8x² Third set: 2x·7=(2·7·x) which is 14x Final equation is 6x^3+8x²+14x
Multiplying Nomials:
Problem: 2x(3x²+4x+7)
First set: 2x times 3x²=(2·3·x·x·x) which is 6x to the third power.
Second set: 2x·4x=(2·4·x·x) which is 8x²
Third set: 2x·7=(2·7·x) which is 14x
Final equation is 6x^3+8x²+14x
